5.9 Global Input

The Global Input settings influence the generation and handling of Six Degrees of

Freedom (6DoF) messages that can be distributed to several Viz Engines.

6DoF is used when working in 3D space in combination with special input devices such

as a mouse. A mouse uses two coordinates (xy) which Viz is able to translate into three

coordinates (xyz) based on a grid.

• Group: Defines which multicast group the generated or received messages belong

to. If more than one group is to be defined, a unique Group number must be set for

each group.

• Role: Defines how messages are generated and processed. Alternatives are; None,

Master and Slave.

• None: Messages are only generated and processed on the local Viz Engine.

• Master: A Master creates messages for himself and the defined group.

• Slave: A Slave reads and processes 6DOF messages but is not allowed creating

them.

• Synch. Properties: Activates/deactivates synchronization of Viz Engine scene

properties.

To synchronize multiple Viz Engines

1. Start Viz Config on all involved render machines.

2. Set the same Group ID for all engines, and set Synch. Properties to Active.

3. Save and close all Viz Configs.

4. Open the Control Panel on all render machines, and make sure that you deactivate

all unused network connections.

• Viz Engine always uses the first network connection setup by the Windows

operating system.

• Synchronized engines work within the same network segment only because it

is using multicasts, hence, it is important to use the right connection.

• You can also determine the first connection by setting a manual metric in

Windows: http://support.microsoft.com/kb/299540.

5. Start all Viz Engines again.

6. Create a simple test scene with a geometry and the Synchronized Properties

plugin (Built Ins > Container > Global) on the same container.

7. Save the scene and open it on all involved engines.

8. Move the geometry on one engine.

• All the other engines will show the same object movement.
